Question

square root(x+10)+8=3

Answer 1

square root has to be positive, isn't it?

Answer 2

\[\sqrt{x+10} + 8 = 3\]
\[\sqrt{x+10}=-5\]
\[x + 10 = (-5)^{2}\]
\[x+10=25\]
\[x=15\]

Answer 3

if you swapped the answer around the equal sign in the equation, both signs would change with it, making it true anyway
